The Alcoa Smelting Process is an alternative to the Hall-Héroult process for the production of aluminum. While it is not in use today, Alcoa operated a commercial scale smelter in East Texas for almost ten years before closing it due to various operational problems. It is a very energy efficient process, using 30-40 percent less electricity than the Hall-Héroult process. If only minor changes to the original design were made, it may be the only alternative process likely to succeed commercially.

Humanity is becoming more confident in exploring space, and Cosmonautics has long become an indispensable branch in people's lives. This book will tell you about how humanity has made its first steps in conquering outer space. About how the first rocket took off, how the first spacecraft sent its signal to Earth, how people flew into space, how different countries, such as the USA, the European Union, China, Japan, India, Russia, master space technologies, and as well as many other things related to human activities in the Earth’s orbit. The book contains more than 120 illustrations, of which more than 20 illustrations of space rockets and more than 40 illustrations of other spacecraf ...

The book “The Logic of More - Applications in Non-binary Machine Logic” is the first comprehensive book focused on the implementation of non-binary switching functions in computer devices and digital machines. It is based on a series of patented non-binary inventions, ranging from arithmetic, memories, to error correcting coders and decoders and encryption and decryption methods. Besides explaining novel non-binary machine logic the book also provides a fresh and unusual but extremely useful view on classical aspects of digital circuits such as memory latches, correlators, multipliers and data scramblers and descramblers. It ends with a chapter on alternate finite fields GF(n). Many s ...

The author of "The Proxy Robotics Trust Patents and Intellectual Property" is a pioneer in this field and inventor of record for each of the patents described in the book. As a portfolio of the holdings of The Proxy Robotics Trust, Sections 1-5 of this book briefly describe five proxy robotics patents already granted by the U.S. Patent and Trademark Office, with each introduction followed by a copy of the complete patent. Sections 6-8 similarly describe three pending U.S. patents in the field, and each section includes a full copy of the U.S. Patent Office's preliminary publication of the pertinent application. All patents and intellectual property of The Proxy Robotics Trust are availa ...

Have you ever wondered what it takes to deal with variable speed drives? Royce Mitchell's book, "Things You Need to Know About Variable Speed Drives," has insight on everything from removing an old drive to replace with a new one to designing an interface, to peripherals to help run your drive. Novices to electrical engineers can find information that helps them understand the requirements related to dealing with variable speed drives.

Repair or replace a missing footpedal switch for your USA Vox amplifier - a Beatle, Royal Guardsman, Viscount, Buckingham, Cambridge, Berkeley, Pacemaker, or Pathfinder. Contains instructions, advice, and construction details to fix one or make a new one, including parts sources. Anyone modestly skilled at electronics construction should be able to follow the instructions and make their USA Vox amplifier footswitch work again. Note: UK Vox amplifiers and Vox amps built by Korg are not covered; only the USA Vox amps built by Thomas Organ in the 1960s and 1970s.

Top Energy Technologies for Emerging Countries (TETEC) ranks the top 5 power generation technologies that will yield the greatest benefit when implemented in any emerging country. There are many power generation technologies in the market, and many of them perform well, but not all are a good fit for implementation in developing countries. Emerging countries face many issues due to the lack of reliable energy technologies that are significant to the growth of their economy, and to the survival of their people — these issues must be taken seriously. Implementing technologies that will help alleviate some of those issues that are sustainable will be of immense help.

If American merchant mariners stayed home, US Navy warships would grind to a halt in 10 days A longshoremen strike- on the US West Coast alone- would cause $2 billion per day in lost GDP Who are these men and women of consequence? Read about them in Doug Squirrel’s True Mariner

The V1141 Beatle Repair Supplement contains information helpful in repairing the Thomas Organ Vox V1141 "Beatle" guitar amplifier. It extends the more general how-it-works information contained in the Vox Owner's Safety Net with V1141-specific schematics, parts lists, board diagrams and other info on this one model. It is much more than a copy of the original factory schematics, and includes entirely redrawn schematics and board diagrams as well as working voltages taken from simulations of the circuits. This allowed sidestepping the occasional error in the original Thomas Organ service information. This information is suitable for the owner of a Beatle who wants to keep his amp runn ...

The V1181 Westminister Repair Supplement contains information helpful in repairing the Thomas Organ Vox V1181 "Westminister" bass amplifier. It extends the more general how-it-works information contained in the Vox Owner's Safety Net with V1181-specific schematics, parts lists, board diagrams and other info on this one model. It is much more than a copy of the original factory schematics, and includes entirely redrawn schematics and board diagrams as well as working voltages taken from simulations of the circuits.
